| Fundamental Research on Soil Water Sampling Technology |
| Soil water sampling technology is of great application significance in the field of environmental geology, especially in such aspects as pollutant migration and accumulation in the unsaturated zone, pollution prediction,prevention and control in shallow groundwater, improvement of saline soil and agroecological study. Based on experimental data, this paper emphatically studies the relationship between soil water extraction amount and soil moisture content in four different kinds of lithology when the soil water sampler is used, the relationship between soil water extraction amount and soil suction in each kind of lithology. The correlation equations are also formulated. Finally, some major factors affecting sampling velocity and soil water- extracting quantity are analyzed. |
